Payroll glossary: the terms every employer should know

This payroll glossary defines the terms that appear on a payslip, a contract or a tax form, from accrued time off and base pay rate to W-2 forms and zero-hour contracts, in plain language you can use immediately. It's the companion reference to our guide on how global payroll works, and it groups every term into five practical areas: pay and rates, taxes and contributions, benefits and deductions, contracts and worker types, and the systems and abbreviations you'll see on a pay stub.

Pay and rate terms describe how compensation gets structured and calculated, covering base pay, overtime, commission, bonuses, and the wage floors behind minimum and living wage rules.

The base pay rate is the amount an employee earns before any additional payments, such as bonuses or overtime. It's the agreed-upon starting wage, set as an hourly rate, a daily rate, a piece rate based on items produced or tasks completed, or a fixed salary per pay period.

A bonus is an extra payment given to employees on top of their regular salary, usually as a reward for performance, company profits, or retention. Bonuses are taxable, and inconsistent payments can cause dissatisfaction, so employees need to understand eligibility and payout schedules to manage their finances.

Commission is variable pay based on an employee's sales performance, used in sales roles to drive productivity. Employees earning commission may receive a base salary plus commission or depend entirely on it, which raises earnings potential but also income instability.

Compensation means an employee's total earnings, including salary, bonuses, benefits, and incentives. It represents the full value an employer offers in exchange for work, so employees should weigh the whole package rather than base salary alone.

Gross pay is an employee's total earnings before any deductions, including base salary, bonuses, commissions, and overtime pay. Employers must keep gross pay calculations accurate to maintain payroll accuracy and comply with tax regulations.

Holiday pay is extra money employees receive for working on official holidays, such as Christmas, New Year's, or Thanksgiving. It raises payroll costs for employers, which is why some companies close on holidays instead, while others operate with a smaller staff and pay the premium rate shown in the table above.

An hourly wage is the amount a worker earns for each hour worked, so pay matches the time actually spent on the job. Hourly workers also receive overtime pay for extra hours, giving them less week-to-week income stability than salaried employees who get a fixed paycheck.

Incentive pay is extra money given to employees as a reward for hard work and strong performance, such as salespeople earning extra for beating a sales target. Employers use bonuses, commissions, or profit-sharing as incentive pay to boost motivation, though it can also create pressure among coworkers.

A living wage is the minimum amount a worker needs to cover basic living expenses, such as food, housing, healthcare, and transportation, based on the real cost of living in a specific area. This differs from the minimum wage, which is set by government rather than local cost of living, and some companies pay a living wage voluntarily to attract and retain skilled employees.

The minimum wage is the lowest hourly pay rate employers are legally required to pay, set by governments so workers can afford basic living expenses. It varies by country, state, and industry, and employers who pay below it face penalties, fines, or legal action.

Net pay is the final amount an employee receives after taxes, health insurance, retirement contributions, and other deductions are taken out of their paycheck. Also called take-home pay, it's always lower than gross pay, and employers provide pay stubs showing how it's calculated.

An off-cycle payment is any payment made to an employee outside a company's regular payroll schedule, including bonuses, commissions, corrections for payroll errors, or severance pay. For example, an employer issues an off-cycle payment to correct an underpayment caused by a mistake, which gets employees their correct earnings but adds processing time and administrative cost.

Overtime pay is extra money given to employees who work beyond their regular hours, calculated at 1.5 times the employee's standard hourly wage in most cases. Some jobs pay double time for overtime worked on holidays or weekends, and employers must follow labor laws to compensate workers properly.

Take-home pay, also known as net pay, is the amount an employee actually receives after federal and state income taxes, Social Security, Medicare, health insurance premiums, retirement contributions, and other withholdings are subtracted from gross earnings. Understanding take-home pay helps employees budget, since it shows the actual amount available to spend.

Vacation pay is wages paid to employees during their approved time off, letting workers take a break while still receiving regular income. Some companies provide a fixed number of paid vacation days a year, while others let employees earn vacation hours based on time worked, and it's required by law in some countries and offered as a company benefit in others.

Variable pay is compensation that changes based on an employee's performance, achievements, or company profits, including bonuses, commissions, and incentives, unlike a fixed salary. It encourages productivity since higher performance leads to higher earnings, though income isn't guaranteed and can fluctuate.

A year-end bonus is an extra payment given to employees at the end of the year, based on company profits or individual performance, as a reward for their contribution to business success. Some companies pay a fixed bonus, others base it on revenue, performance, or tenure, and year-end bonuses are taxable and never guaranteed.

Year-to-date (YTD) earnings are the total income an employee has earned from the beginning of the year to the current date, including wages, overtime, bonuses, and other compensation before deductions. Employers use YTD figures to calculate taxes and benefits, and employees check YTD earnings on pay stubs to confirm accuracy.

Tax and contribution terms cover the forms employees complete and the taxes employers withhold and remit on their behalf, from the W-4 filled out at hire to the payroll taxes filed every pay period.

The W-4 form is a tax document employees fill out when they start a new job, telling employers how much federal income tax to withhold from each paycheck based on filing status and allowances. Some states have their own version for state income tax, and employees can update it anytime, especially after a major life event such as marriage or having a child.

FICA stands for the Federal Insurance Contributions Act, which covers Social Security and Medicare taxes that fund retirement benefits, disability income, and healthcare for eligible individuals. Employers deduct a portion from employee wages and contribute a matching amount, and businesses report this liability, together with Federal Income Tax (FIT), to the IRS every quarter on Form 941.

Income tax is the money deducted from a worker's wages and paid to the government to fund public services such as schools, hospitals, and roads. Employers are responsible for withholding the correct amount and sending it to the tax authorities; workers who overpaid receive a refund at year end, while failing to pay required tax results in penalties.

Medicare tax is a mandatory payroll tax that funds healthcare services for people aged 65 and older in the United States, with both employees and employers contributing a percentage of each paycheck. High-income earners pay an additional Medicare tax on top of the standard rate.

Payroll taxes are the deductions taken from an employee's wages to fund government programs such as Social Security, Medicare, and unemployment benefits, matched by an equal employer share. Employers must calculate and submit payroll taxes accurately to avoid penalties, and rates and filing rules differ widely by country; see payroll taxes across countries for a fuller comparison.

Social Security tax is a payroll tax that funds retirement, disability, and survivor benefits for eligible individuals, paid by both employees and employers, or in full by self-employed individuals. Contribution rates vary widely by country: employer social security contributions have a median of 12.6% per our Global Employer Burden Index dataset (196 countries), with New Caledonia the highest at 36.49% per our Global Employer Burden Index dataset, while employee contributions have a median of 7% per our Global Employer Burden Index dataset (191 countries), with Romania the highest at 35% per our Global Employer Burden Index dataset.

Taxable income is the portion of a person's earnings subject to taxation after deductions and exemptions, including wages, bonuses, and other earnings, but excluding tax-free benefits such as employer-provided health insurance. Reducing taxable income through retirement contributions, deductions, or exemptions lowers what's owed.

Unemployment tax is a payroll tax employers pay to fund unemployment benefits for workers who lose their jobs, providing financial aid to employees who are laid off or terminated without fault. Employers contribute to this tax, and in some regions employees pay a portion too; the rate varies by factors such as company size and past layoffs.

A W-2 form is a tax document employers give employees at year end summarizing total wages earned, Social Security and Medicare taxes paid, and income tax withheld. Employees use it to file tax returns and find out whether they owe additional tax or qualify for a refund, and employers must send W-2 forms by January 31 each year.

Withholding tax is the portion of an employee's income an employer deducts for tax purposes, covering federal, state, and local taxes, before sending the withheld amount to the government on the employee's behalf. The amount withheld depends on salary, filing status, and deductions claimed: too much withheld means a refund, too little means owing more at filing time.

Benefits, leave and deduction terms cover the amounts subtracted from a paycheck and the paid or unpaid time employees accrue outside of base pay, from garnishment orders to retirement contributions.

Accrue means to build up or accumulate something over time, most often paid time off such as vacation days, sick leave, or personal time. Many employers let employees accrue time off based on hours or days worked, so the longer they work, the more time off they earn, while other companies give a set number of days upfront instead.

Deductions are amounts subtracted from an employee's paycheck for taxes, insurance, retirement contributions, and other expenses. Necessary deductions include income tax and social security, while voluntary deductions cover things like health insurance and savings plans, and employees should check pay stubs to see how deductions affect take-home pay.

Fringe benefits are additional benefits provided to employees beyond regular wages, such as company cars, gym memberships, or tuition reimbursement, and they increase job satisfaction and help attract talent. Some fringe benefits are taxable, so both employers and employees need to understand their financial impact.

Garnishment is a legal process where a portion of an employee's wages is withheld to repay debts, such as child support, unpaid loans, or tax obligations. Employers are legally required to comply with garnishment orders and deduct the specified amounts from the paycheck, and employees facing wage garnishment should seek financial advice to manage their money.

Leave Without Pay (LWOP) is when an employee takes time off but does not receive wages during that period, used for personal reasons, extended vacations, or medical emergencies when paid leave options are unavailable. Employees keep their job and, depending on company policy, benefits such as health insurance, but extended LWOP also reduces overall earnings and retirement contributions.

A pension plan is a retirement savings program that provides income to employees after they retire, funded by contributions from both employer and employee that grow over time through investments. There are two main types: defined benefit plans, which guarantee a fixed income, and defined contribution plans, where the payout depends on investment performance.

A qualified plan is a retirement savings plan that meets government tax regulations and offers tax benefits to both employees and employers, including 401(k) plans and pension plans. Qualified plans are regulated by tax authorities to enforce contribution limits and distribution rules, and withdrawals before retirement age trigger penalties.

Reimbursement is money an employer gives back to employees for work-related expenses, such as travel costs, office supplies, and work-related meals, once the employee submits receipts or reports. Reimbursements aren't taxable, since they're considered work-related costs rather than income.

A retirement contribution is money set aside for an employee's future retirement, typically a portion of salary paid into a plan such as a 401(k) or pension fund. Many employers match a percentage of these contributions, and the money grows tax-deferred, meaning employees pay tax on withdrawals later; early withdrawals usually carry penalties.

Severance pay is money given to employees after they lose their jobs due to layoffs or company restructuring, providing temporary financial support while they look for a new job. The amount depends on the employee's salary and years of service and is taxable as income. Statutory notice periods before termination also differ by country: the median is 4.3 weeks per our Global Employer Burden Index dataset (198 countries), with Gambia requiring the highest at 26 weeks per our Global Employer Burden Index dataset. For a fuller country-by-country comparison of termination costs, see the termination cost index.

Union dues are fees deducted from an employee's wages for being part of a labor union, which negotiates wages, benefits, and working conditions on behalf of workers. The amount deducted depends on union agreements and employee earnings, and in some regions employees choose whether to join a union, while in others membership is required.

Contract, schedule and worker terms classify how employees are engaged and paid, from exempt and non-exempt status to job classification and zero-hour contracts.

An exempt employee is someone who does not get extra pay for working overtime because of their job type, receiving a fixed salary and expected to complete their duties regardless of hours worked. Exempt status provides income stability but can mean long hours without extra pay, and employers must follow labor laws to prevent misclassification.

Job classification is the process of grouping employees based on their job roles, duties, and responsibilities, which helps companies organize their workforce, set fair wages, and follow labor laws. Jobs are commonly classified as entry-level, mid-level, or senior positions, each with different pay scales, and the system shapes benefits, promotions, and career growth.

A key employee is someone who holds an important position in a company and is highly valuable to its success, often due to specialized skills, leadership roles, or important responsibilities. These employees may receive higher salaries, bonuses, or extra benefits such as stock options and retirement plans, and companies often carry insurance policies to protect against losses if a key employee leaves or becomes unable to work.

A non-exempt employee is a worker who must be paid extra for overtime under labor law: if they work more than the standard 40 hours a week, they're paid at 1.5 times their regular hourly wage. Non-exempt employees typically hold hourly-wage positions in industries such as retail, hospitality, and manufacturing, and employers must track their hours accurately to comply with wage laws.

A zero-hour contract is an employment agreement where an employer does not guarantee a set number of work hours, and employees are paid only for the hours they actually work. Zero-hour contracts are common in industries such as retail, hospitality, and gig work, offering flexibility for both sides but causing income instability since workers don't get consistent hours.

Systems and reporting terms cover the payment rails, performance metrics, and abbreviations you'll see in payroll software and on a pay stub, such as ACH transfers, direct deposit, and KPI tracking. Several of these acronyms have their own full entries elsewhere in this glossary; the table below is a quick-reference list for reading a pay stub or a payroll system screen.

ACH, or Automated Clearing House, is an electronic system that lets banks and credit unions transfer money securely, used for direct deposit payroll, bill payments, and other financial transactions. Employers send salaries directly to employees' bank accounts instead of using paper checks, which makes payments faster and safer, and ACH transactions are automated and regulated, which reduces errors and keeps payments secure.

Direct deposit is an electronic payment method where wages are transferred directly to an employee's bank account, removing the need for physical checks and reducing administrative costs. It improves security and convenience for both sides, though it requires an active bank account and sometimes involves processing fees.

A Key Performance Indicator (KPI) is a measurable value used to assess an employee's work performance, set by businesses to track progress toward goals and see whether employees are meeting expectations. For example, a sales KPI might be the number of new customers gained in a month, while a customer service KPI might be response time to inquiries, and employees who meet or exceed their KPIs often receive bonuses or promotions.

Once you're comfortable with the terminology, the next step is comparing how providers actually handle these processes. Our review of the best global payroll providers breaks down pricing, coverage and features side by side.
